Has Science Served Us Well When It Comes To The Prevention and Early Detection Of Cancer?

by Dr. Len May 02, 2012

As I write this, I am returning from a trip to Los Angeles where I participated yesterday in a panel discussion on the topic of cancer prevention and early detection. The occasion was the 2012 Global Conference sponsored by the Milken Institute. (If you are not familiar with this conference, it is probably one of the premier finance and investing conferences in the country, if not the world. And the luminaries in attendance--both as attendees and speakers--were a testament to the influence of the Institute and its founder, Michael Milken.)

 

I was on this panel through an invitation from the Melanoma Research Alliance and its chief executive, Wendy Selig, a former colleague of mine when she was at the American Cancer Society Cancer Action Network.  Other participants included Dr. Stephen Gruber, who is the recently appointed director for the USC Norris Comprehensive Cancer Center in Los Angeles, Dr. Sancy Leachman who is the director of melanoma and cutaneous oncology at the Huntsman Cancer Institute in Salt Lake City, and Sherry Lansing who is the CEO of a foundation of the same name and a well-known cancer research advocate (she is very well known in the entertainment industry as the former head of Paramount Pictures and one of the people who conceived of Stand Up To Cancer which has done much to transform the landscape of cancer research in this country).

 

What made this event more interesting was that the audience was made up of those same financial and investing folks I mentioned above. As you might imagine, almost all the sessions were devoted to topics very relevant to their professional interests. The topic of the session I participated in was a bit off the usual target of the meeting. This session was not about investing--it was about health. I must admit that I was surprised at the number of attendees who joined us for our discussion, and even more pleasantly surprised that they remained engaged throughout our 90 minutes.

 

In what would have otherwise been a fairly typical recitation of facts about how cancer prevention and early detection can reduce the burden and suffering from cancer, a theme emerged: we as professionals are not doing our best in clarifying our advice about the prevention and early detection of cancer through cancer screening.

 

When you are sitting in a room with some very intelligent people realizing that our lack of clarity and conflicting recommendations on advising people what they need to do about their health, you begin to understand that we are facing a dilemma that could have a significant impact on how successful we are going to be in getting people to take action to reduce the risk of cancer or finding it early.

Weight And Inactivity Are Threatening To Overtake Tobacco As Risk Factors For Cancer According To Annual Report To The Nation

by Dr. Len March 28, 2012

The "Annual Report to the Nation on the Status of Cancer" was released this afternoon as has been the case every year since the first report was issued in 1998. And, like many of the reports previously, we are fortunate to continue to see declines in the rates of deaths for many cancers along with a decrease in the frequency of some cancers.

 

However, the news is not all good.

 

Unfortunately, the incidence of some cancers continues to increase. And, as explained very clearly in this excellent report, this nation continues to suffer from an epidemic of overweight, obesity and physical activity that the authors suggest-but don't actually say-has the potential to overcome the favorable impact of declining smoking and tobacco use on cancer incidence and deaths. The implication is clear that if we don't do something-and do something quickly-to reverse the trend we will see incidence and deaths from certain cancers continue to increase in the future.

 

And I would stress the point that it is no longer just being oversized that increases your risk of cancer, but also sitting all day on the job (like I am doing right now) as another factor that plays into your cancer risk, independent of how large or small you may be. More...

Cancer Facts and Figures 2012: One Million Cancer Deaths Averted, But We Still Have A Long Way To Go

by Dr. Len January 04, 2012

Welcome to the New Year!

 

And as has been the case for many years in the past, the American Cancer Society takes the New Year opportunity of providing the nation with the latest estimates of cancer incidence and deaths, along with a measure of how well we are doing in reducing the burden of cancer in the United States.

 

The data is contained in two reports released today by the Society: the consumer oriented Cancer Facts and Figures 2012 and the more scientifically directed Cancer Statistics 2012. Both are available online. 

 

It is never "good news" to realize that the burden of cancer in this country is immense. And with the country gaining in population and age, the extent of that burden is inevitably going to increase. But this year's report does contain some welcome information, namely that cancer death rates have declined in men and women of every racial/ethnic group over the past 10 years, with the sole (and unfortunate) exception of American Indians/Alaska Natives. In addition, the Society now estimates that a bit more than one million cancer deaths (1,024,400 to be exact) have been avoided since 1991-1992.

 

That one million number is actually more significant than it seems. Many of the people in that 1 million never heard the words "you have cancer." Maybe they had a colon polyp removed before it became cancerous, maybe they stopped-or never started-smoking. Maybe they had a pap smear that found a pre-cancerous lesion. And then there are the patients who have benefitted from the advances in cancer treatment that have occurred over the past number of decades.

 

But the 1 million number also means that these are people who have hopefully remained active and engaged in life, loved by their families, productive in their communities. In economic terms, the return on investment on avoiding those one million deaths may likely be incalculable. In human terms, it is an amazing accomplishment. More...

A Researcher Says The Best Strategy To Impact Breast Cancer Is To Stop Mammography, And No One Cares?

by Dr. Len November 22, 2011

The announcement today from Canada that women should severely curtail their use of screening mammograms for the early detection of breast cancer and discontinue regular clinical examinations and self-breast examinations was interesting in and of its own. But the editorial that accompanied that announcement-from a long-time avowed skeptic of the benefits of screening mammograms-took the debate to a new level. Whether that level was higher or lower is a matter of personal interpretation, but in the editorial was the statement that abandoning breast cancer screening is the most effective way we have to reduce the risks of breast cancer. The statement, highlighted in an accompanying press release (http://www.eurekalert.org/pub_releases/2011-11/cmaj-nbc111611.php) was, in short a stunner.

 

What is even more amazing is that there hasn't been much reaction to that statement. And keep in mind that just two days earlier, the medical journal The Lancet published a letter from an international  group of experts in breast cancer screening who raised the issue of an organized anti-mammography campaign orchestrated in part by the head of the Nordic Cochrane Centre, headed by none other than the physician who wrote the editorial. But from where I sit-a place that is usually the epicenter of these discussions-there has in fact been very little reaction. No media, no frantic calls, no running to man the barricades. Essentially, nothing.

 

I find that hard to understand for a story with this degree of impact. Maybe we are all just worn out from the screening debates, after several years of indecision about the benefits of mammograms, the frequency of pap tests, and the big debate recently about whether or not prostate cancer screening really saves lives.

 

For me and others I know, there is increasing concern that the value of screening for the prevention and early detection of cancer will get lost in the morass of conflicting comments, and that we might be at risk of turning off the public to the benefits of screening for cancer, and perhaps lives will be lost in the process. And that would be shameful. More...

To Screen Or Not To Screen: The Prostate Cancer Dilemma

by Dr. Len October 07, 2011

To screen or not to screen for prostate cancer, that is the question. Or is it?

 

A report from the venerable United States Preventive Services Task Force (USPSTF) made it to the media yesterday--a bit ahead of schedule--and it not only says we aren't certain whether a man should get a PSA test to find prostate cancer early, it came flat out and said, effectively, "Don't do it!"

 

Now that is a recommendation that is going to create a good deal of discussion, I would think. More...

A Declaration for the World, A Noble Mission For All

by Dr. Len September 20, 2011

There are few times in life when one gets to watch history being made. Today is one of those times.

 

I am in New York with a number of colleagues from the American Cancer Society and other committed organizations to observe a UN High Level Meeting which will--at long last--put non-communicable diseases on the international agenda. The impact of the decisions made here over the next two days can indeed change the face of global health forever. More...

Extrapolated Science: Headlines Don't Reflect The Results In Recent Report On Screening Mammography

by Dr. Len September 08, 2011

Please, please, please say it's so...

 

That was my initial reaction today when I saw news stories about a study presented at a breast cancer conference sponsored by a number of leading organizations with a professional interest in the diagnosis and treatment of breast cancer.

 

The headlines were pretty clear, to the effect that the study showed the value of screening mammography in women between the ages of 40-49. The accompanying stories suggested that this research essentially repudiated the recommendations of the United States Preventive Services Task Force initially published in November 2009.

 

You may remember that event, since it created a huge amount of media and public interest when the Task Force suggested that screening mammograms to find breast cancer early should not be done routinely in women between the ages of 40 and 49. This was a change from its prior recommendation, and was in conflict with the opinions of the American Cancer Society and other organizations which conitinued to endorse routine breast cancer screening in this age group.

 

There has been a lot of water under the dam since then, and there have been additional scientific studies reported about the value of screening mammograms, some of which support breast cancer screening and others which do not.

 

Enter the reports this week that a study from Michigan suggests that screening mammograms and breast self-examination in women between the ages of 40 and 49 results in earlier diagnosis and less disfiguring treatment.

 

When I read the headlines and the news reports, I quickly came to the conclusion that there was a possible disconnect between what the reporters concluded from the study and what I thought was scientifically valid.  Mind you, I read these things with my own bias/conflict of interest: I have been a supporter of mammograms for women between the ages of 40-49, and believe they save lives in this age group. But my problem here is whether this particular research actually supports that position, as the press reports suggested.

 

Guess what? I don't think it does. More...

Welcome to the World, Rayna Analiese--and Looking Forward to Many Happy Birthdays!

by Dr. Len August 10, 2011

(A letter to my newborn granddaughter)

 

Good morning, Rayna Analiese. Welcome to the world!

 

You are a teeny 8 pound 8 ounce bundle of beauty and joy who arrived yesterday afternoon at 1:32 PM CDT--100 years (almost to the very day) after one of your great grandmothers was born. 

 

Grandpa--who is normally not a big lover of babies--went gaga over you. "So cute! So cute!" is about all he could say as he snuggled you in his tall arms--afraid all the while that he might drop this football-size bundle of love.

 

You have lots of people who love you, and lots more who are going to love you--not to mention all the people who love you who haven't had a chance to meet you in person yet. You have aunts and uncles and great aunts and uncles and grandmothers and grandfathers and great grandmothers to boot--and don't forget your great-great grandmother who will squeeze you tight. You are going to have to get used to the large family feasts filled with all sorts of nasty food when you come home from time to time to parade your cute little bonnets around the many houses you will have to visit. Mom and Dad are certainly going to have fun on those trips.

 

But I wouldn't be me if I didn't think for a moment about what your new life means, so forgive me for a moment while I ponder the meaning you bring into our lives, especially for Grandma Sandra and Grandpa Len. More...

Cancer Facts and Figures 2011: Poverty is a Carcinogen. Does Anyone Care?

by Dr. Len June 17, 2011

"Poverty is a carcinogen."

 

Those were the words of Dr. Samuel Broder when he was director of the National Cancer Institute in 1989.  

 

As amply documented in the annual "Cancer Facts and Figures 2011" released today by the American Cancer Society, cancer shows that poverty remains one of the most potent a carcinogen-rivaling tobacco and obesity-as we have ever seen.

 

We have heard lots and lots about how cell phones and Styrofoam cause cancer.  But do you hear anyone talking about the huge impact of poverty and limited education on cancer?

 

If you don't hear anything about a true carcinogen that statistics show causes 37% of the deaths from cancer in people between the ages of 27 and 64, then maybe you have the answer to a very important question: If we are serious about reducing the burden and suffering from cancer, why aren't we paying attention to those most in need?

The Genomic Era: We Have Reached A New Tipping Point In Cancer Research And Treatment

by Dr. Len June 06, 2011

I don't often write blogs about articles that appear in newspapers, but in this case I am going to make an exception for today's excellent front page story in the Wall Street Journal by Ron Winslow discussing the coming of age of genetics and genomics in diagnosing, treating and predicting the behavior of the disease we now know as cancer.

 

But even though Mr. Winslow may have pre-empted the thought that for me the seminal theme of this year's annual ASCO meeting in Chicago was related to the impact of genetics on cancer research and treatment, his well-written "scoop" won't prevent me from weighing in with my opinion that this year represents another one of those seldom moments when we reach a tipping point in cancer research and the application of that research to the diagnosis and treatment of cancer.

 

It was obvious literally from very beginning of the meeting when Dr. George Sledge--the President of ASCO--addressed thousands of cancer professionals from around the world and talked about the impact of the forthcoming era of personalized medicine.

 

In the past, we have had the chemotherapy era, where we were able to put combinations of toxic drugs together to cure and control some forms of cancer.  We have had the adjuvant era, when we learned that using chemotherapy could delay the progression of cancer after primary treatment, usually surgery.  We have most recently had the targeted therapy era, when we learned that drugs targeted at genetic changes in cancer cells could impact survival, sometimes substantially.  We wish we had a vaccine era, although there have been some practical successes and hopeful research that continues in that arena.

 

And now we have the genomic era. More...
